Gear Milling

Gear milling is a multipoint machining process in which individual tooth spacings are created by a rotating multiedge cutter having a cross-section similar to that of the generated teeth (involute).  After cutting each space, the gear is returned to its original position, and the gear blank is indexed for the next cut.

Process Characteristics

Uses a rotating form cutter
Gear blanks are indexed after each cut
Gear teeth are produced individually
Requires deburring
Is a low production process
Is normally used only when generating processes (i.e., hobbing, shaping) are unavailable
